“…This finding also suggests that OOCs may originate from the oral epithelial component, whereas KCOTs originate from dental lamina (13). This would explain the occurrence of KCOTs in the posterior mandible, where the dental lamina is more active at the age that patients develop this lesion (1). In addition, the unusual histopathological findings of the present case (lichenoid changes and basilar hyperplasia) can be explained by the suggested origin of the OOC.…”

“…In addition, the unusual histopathological findings of the present case (lichenoid changes and basilar hyperplasia) can be explained by the suggested origin of the OOC. Additionally, less significant expression of p63 in OOCs compared to KCOTs suggests a lower proliferative and self-renewal potential for OOCs (1,14), which may explain the different clinical behaviors between OOCs and OKCs.…”

Introduction: The orthokeratinized odontogenic cyst (OOC) is an uncommon developmental cyst that occurs between the second to fifth decades, more commonly in males. It is a solitary lesion that mostly occurs in the mandible rather than the maxilla. Histologic features include a thin, uniform epithelial lining with orthokeratinization and a prominent granular layer below a noncorrugated onion-skin-like surface. Case Presentation: A 40-year-old man presented with pain and swelling in the left mandibular canine molar area. The panoramic radiograph revealed a well-defined radiolucency extending from the left mandibular canine to the left mandibular molar, with scalloped projections between the teeth roots. Microscopic examination showed a cystic lesion lined by an orthokeratinized stratified squamous epithelium, and a prominent granular layer beneath the cornified layer was seen. The features were those of an OCC. Conclusions: From the demographic and radiographic perspectives, the features of OOCs can be similar, but more variation can be found on routine histopathological analyses.

“…Considering the low recurrence and lack of aggressiveness, OOCs should be treated by conservative approach with complete enucleation along with the removal of impacted tooth. [ 5 10 15 ] However, thorough sampling of specimen is required as the presence of parakeratinization and polarization should lead to the lesion being diagnosed as OKC that requires aggressive treatment. [ 5 ] The recurrence rate OOC is 2.2% which is far low than that of KCOT (recurrence rate 42.6%).…”

Orthokeratinized odontogenic cyst (OOC) is a relatively rare odontogenic cyst, distinct from odontogenic keratocyst (OKC). In the 4th edition of WHO Classification of Head and Neck Tumors (2017), OOC has been included as a separate entity in the category of developmental odontogenic cysts. It presents as a unilocular radiolucent lesion in the posterior mandible and is frequently related to impacted teeth, thus mimicking dentigerous cyst. Due to low local aggressiveness and no association with nevoid basal cell carcinoma syndrome, it does not show tendency to recur. When compared to OKC, OOC exhibits substantial number of differences with respect to clinical, pathological and behavioral features and treatment modalities. Hence, recognizing OOC as unique lesion is mandatory to avoid unnecessary overtreatment. This paper aims to report a rare case of OOC associated with impacted tooth, showing calcifications and emphasizes its differences from OKC. Furthermore, the recent concepts about OKC and OOC are discussed.

“…The suprabasilar areas often loosen up giving the appearance like a stellate reticulum [15]. OKC shares similar characteristics with Orthokeratinized odontogenic cyst with respect to age of occurrence and site, yet these two lesions differ in their biological activity [16] OKC'S tend to grow in antero posterior direction within the medullary cavity of the bone and may cause an obvious bone expansion [13]. A hazy radiolucent lumen can be seen on a conventional radiograph which is suggestive of a dense proteinacious material such as keratin.…”

The Odontogenic keratocyst (OKC) is a developmental, non – inflammatory chronic cystic lesion, on radiograph it may be unilocular or multi locular OKC is a cyst of odontogenic origin, usually asymptomatic with an aggressive clinical behavior including a high recurrence rate and tendency to invade bone and adjacent soft tissues. Diagnosis is based on the clinical history, clinical appearance, and radiographs and histology. A case of odontogenic keratocyst involving the ramus of the mandible is presented in this article emphasizing on the characteristics and various features of OKC.
